Click to send data for ui_chart (Bar graphs)

[xraken]

For ui_table, there is a check box for "send data onclick" which is very useful to handle click events on table to show additional information for the clicked row. Is there a way to get the same effect for ui_chart?

not currently no.

Any clues on how I could add that myself? References to related work would help. I tried using the onClick option as documented for chart.js but my callback was not getting called when clicking on the bars.
